I was diagnosed low T at 24 by an endocrinologist (no sides). Went on underground test for a few months and didn't feel any different. I even sent a sample in to janoshik cause I thought I got scammed kek. Maybe it's because I have low t of the brain (type 2 hypogonadism)? (balls work fine but brain doesn't tell them to make t). Stopped cause my balls were getting soft and small. They rebounded just fine though.
